COFFEE MAKER.

Application led April 26,

To all whom t may concern:

Be it known that I, FRANCIS W. GIBSON, a citizen of the United States, residin at IVest Roxbury, Boston, county of Su olk, Commonwealth of Massachusetts, have invented certain new and useful Improvements in Coffee Makers, of which the following is a specification.

This invention relates to weighing apparatus suitable for household use in the proportioning of food ingredients, and is particularly intended for use in measuring the two principal ingredients, coffee and water, involved in the `process of making coffee.

The object of my invention is to provide a simple, inexpensive and accurate device for measuring coffee and water, and in which the supply of coffee may be kept in sanitary condition and preserved against deterioration.

This object, together with certain other features of advantage, is secured in the device of the present invention, the construction and operation of which is disclosed 'in the specification which follows. In the drawings accompanying that specification, I have shown an embodiment of my invention which well illustratesthe principles involved, and is in itself a form found satisfactory in use and Well adapted to the requirements of manufacture. Throughout the specification and drawings, like reference characters are correspondingly employed, and in the drawings:

Fig. 1 is a perspective view of measuring apparatus in accordance with my invention.

Fig. 2 is a plan view of the scale mechanism, and illustrating the manner of attachment of the parts to the supporting structure.

Fig. 3 is a detail view of a portion of the container clamping band, removed.

Fig. 4`is a detail view of the knife edge member of the scale mechanism, removed.

Fig. 5 is a detail 'section through the discharge spout for the container, particularly illustrating the valve mechanism.

I have indicated at 1 a suitable base or attaching member upon which my measuring apparatus may be mounted. The member 1 may be fastened to a wall or other support whereby to dispose the apparatus in conveniently accessible position.

The container 8 for the coffee or other substance to be delivered and weighed, the scale mechanism 2 and 3, the indicator 4 and 1918. Serial No. 230,966.

the measuring receptacle 5 may all be attached to the member 1 in any convenient manner.

As here shown, the container 8 is a jar, preferably of glass so as to visibly expose its contents, having a removable closure 9 for its illingvopening, and having a discharge opening delivering by gravity into a discharge nozzle 7 which is supported upon a bracket 6 projecting horizontally from the member 1. The container 8 may conveniently be an original package having one end removable and insertable into the nozzle 7.

The container is detachably clamped near its upper end to the member 1 by a suitable clamping band 10. One end of this band may be outwardly turned and slotted, as indicated at 11 Fig. 3, for engagement with a screw or the like projecting from the base 1. The other end of the band 10 may be hooked as indicated at 12, Fig. 1, for engagement with a staple 13 projecting from said base 1. The lower end Vof the container seats within the'discharge spout 7' upon a suitable shoulder rformed internally thereof. The bracket 6 has an opening therein through which the restricted end of the funnel-shaped spout or nozzle 7 extends, as best shown in Figs. l and The delivery at 7 may be direct to the scale member or may in case the coffee is supplied in the bean may deliver to an intermediate mill or grinder from which it passes to the weighing device which I shall now describe.

The scale mechanism, indicated generally by rthe numerals 2 and 3 carries the measuring receptacle 5, being suitably adjusted or counter-balanced to compensate for the weight of this receptacle when empty.

As here shown, the member 2 is a simple metallic strip fastened at one end to the support 1, as clearly shown in Fig. 2, and formed with a horizontally extending knife edgell upon which the member 3 is adapted to rock.

' The member 3, as here shown, is formed as a simple metallic strip, comprising a balancing portion 15 upon which a counter Weight 16 is adjustably mounted, and a pair of forked` arms 17, which are slotted as indicated at 18 and formed to fit the knife edge 14.

The arms 17 support the measuring receptacle 5, which may be detachably suspended therefrom in any suitable manner. As here shown, said receptacle is provided with hooks if) vfhich engage over horizontally disposed leveling device Q extending across the top ot the receptacle and' tas-tened at its ends to the arms 17, as clearly appears in ,l-lig. l. The leveling device 2O may be suitably bent between its ends, as shown in llligs. l and 2, uf'hereby to present an extended surit'ace to the coffee or other substance discharging therepast into the receptacle to secure an even distribution in the receptacle 5.

The indicator' l cooperates with the scale member being graduated to indicate in terms ot cup the amount of coiee disciarged into the measuringV receptacle 5. n. convenient vmargin is provided adjacent the graduations for individual indications where personal taste requires more or less cotiee per cup. @ne ot the receptacle-supporting arms 7 may conveniently be extend cd and formed as a pointer 2l to cooperate with the graduations ot the indicator scale ll.

The discharge of coilee from the container 8 into the receptacle 5V is controlled by anyY suitable valve mechanism, which may be so regulated, it desired, that each actuation of the valve will deliver substantially enough coffee to make one cup. As here shown, the discharge is controlled by a valve 22 pivotally mounted Within the res ricted` discharge end of the spout 7 (see Fig. and operated` by any suitable ei;- ternally disposed handle 23. The valve liandle Q3v is providedV with ay turn 231: so disposed to lie dat on the support 2 When the valve is closed. The Weight oi the container therefore tends to close the valve 22 and cut oit1v the delivery ot the coitee. Fur-l thermore, the upward litt ot the container' assists in bringing down a tree delivery.

ln order to prevent the coffee from clogging at the valve, l provide a stirrer 24 which is adapted to be operated` each time the valve is opened and closed, and which thus m ves through the cotlee and keeps it loose. This stirrer may conveniently be a simple coil 0iC spring Wire fastened at one end to the upper tace ot the. gate valve in its movement. The stirrer 24; is preferably also continued upwardly and lei-'t With a free end 21,21 on which a vibrator isv mounted to` keep the contents tree Within the container. lt vvill be noted that the receptacle 5 is termed a cup ot conic shape. The purpose ot this construction is to insure sym-` metrical distribution of the eoliee in the receptacle especially relative to the pivot ot stantrally certain.. The liquid capacity ot the receptacle 5 is graduated in relation to 4a valve in the Weight unit of the scale as to give the proper volume or liquid unit for the Weight unit.

ln the use of my device, the container 8 filled With the coiliee or other substance to be disposed is put in place. The receptacle being hung in place, the balance 16 adjusted (it necessary) until the pointer 2l registers with the. zero niark on the indicator Ll. lVhen the valve 22 is turned by the handle 23 a quantity ot coffee descends by gravity into the receptacle 5, the reading vbeing given 1` terms ot cups by the movement of ,e pointer past the .markings of the indicator l.

llllien a quantity ot coiiee sufficient to malte the desired number ot cups is thus delivered, the valve 22 is again closed,l and the receptacle removed and the known quantity oi coffee mixed With the proper amount of Water.

lit ior example, enough coffee has been delivered into the receptacle 5 to makethree rups oi coiiee. the measured coiiiee is emptied into the coffee pot or other receptacle. and the cup o three times filled substantially, with iva-ter and emptied into the co'lee pot. For practical reasons, ot course, it is desirable that a Water line 25 be marked on` the receptacle 5 to indicate the levelf to which the receptacle shall be filled with Water, rather than attempt to measure by filling to overflowing. 7With coitee of. known grade and kind, and ground to a determinedk tineness. and to which the quantity of Water per cup is related, it is possible by my appa.- ratus to consistently achieve a satisfactory cup ot coilee.
